Hi Gang, First of all, don't trust Yahoo stock data at all. In looking at SOXL and comparing it to Google's there is a section of the historical data that is off by a factor of 4 from the adjusted close! Where the screwed up is where the 4/1 stock split happened. It is wrong from there until 5/20/15 and then it is right.

I just wish Google allowed you to look at history in weekly and monthly in addition to daily. Yeah, I can mark and copy/paste to do it but what a pain in the south end of a donkey headed north.

Then when I looked at the closing prices listed by Yahoo and Google they don't sync exactly It is as though one or the other used a different data point to record the price. ARRRGH!

I went to NASDAQ as well and it differs by a penny or so from time to time from Google, but it too only shows daily figures.

Anybody got a better suggestion where to get data for backtesting?

Best,

Allen
